Arc melted button.
I've been experimenting with a very crude arc melting furnace made from a box of firebrick, an old 275A stick welder, two graphite electrodes, and a small graphite crucible. I melted this button of solid chromium down out of a small pile of the chromium plate described above. Not bad for a $15 furnace (not counting the welder).Source:Theodore GrayContributor:Theodore GrayAcquired:23 August, 2003Text Updated:26 April, 2007Price: $5/poundSize: 3/4"Purity: 99.9%
